The European Commission has accused Google and Apple of violating the EU's Digital Markets Act (DMA), which could lead to substantial fines for the American tech giants.

The commission has preliminarily concluded that Google's search engine favors results linking to its own services over those of competitors, contravening the obligation to treat third-party services transparently, fairly, and without discrimination.

Furthermore, Google Play is charged with hindering developers from directing consumers to alternative channels that might offer better deals.

Apple has been directed to make its operating systems accessible to devices produced by competitors or risk investigations and penalties.

The EU has also provided a comprehensive timeline and methodology for Apple to address requests from app developers seeking to open its systems.

Violations of the DMA can lead to fines up to 10% of global revenue, or 20% for repeat offenders.

Considering Apple's projected revenue for 2024, the maximum penalty could approach $80 billion.

The EU is also looking into Meta, the parent company of Facebook and Instagram, regarding its pay or consent model.

The U.S. has expressed opposition to the EU's regulatory measures, with President Donald Trump signaling that any regulatory actions against American firms will influence his decisions on imposing tariffs on imported goods.
